Springtrap

Springtrap is the result of William Afton being crushed inside a Springbonnie suit by springlocks, only to rot away in a backroom, leaving him to be what he is today. He was originally Springbonnie, entertaining kids in Fredbear's family diner. Despite having Afton inside, he has grown to be his own person, and doesn't let the past get to him, not associating with the murderer any longer.

Appearance
Springtrap is a drab olive color, with darker colors on his stomach and the insides of his ears. A great portion of his right ear is missing, with a single red wire sticking out of the stump. Springtrap's entire body is torn and tattered, with gaping holes bearing exposed wires and caging throughout. His green/brown/black nose has an irregular squarish shape due to deterioration. While both of Springtrap's hands and feet are attached and generally intact, his legs are entirely stripped from the mid-shin down, fully exposing the endoskeleton wiring and metal. Several of his finger joints from each hand are missing their suit overlays. The middle and little fingers of Springtrap's right hand are notably missing their fingertips. A single black button can be seen on the middle of his chest. Above the button sits a purple bowtie, which has clearly torn and molded. If one looks closely at the large hole in Springtrap's chest, there are multiple red streaks, presumably remnants of William Afton's corpse. Springtrap's endoskeleton feet appear wedge-shaped,with each sporting five toes. Both of Springtrap's eyes are properly set inside of his head, and appear to be pale silver in color. Springtrap has a wide, permanent grin, as the material surrounding his teeth has deteriorated. Despite having tried her best to clean him of the remains of Afton, Noa found Springtrap needed some parts to stay stabilized, and so some bodily remains still are stuck inside to this day. When Afton takes control of the body, his eyes turn a bright purple.

Personality
Springtrap is a monotone, yet sassy guy. Having been around for quite a long time, he knows full well how life works, and cant help but laugh at the younger partners he's surrounded with and their mindsets. behind the snarky comments and rude attitude towards everyone, he is extremely protective over the only person he cares about, and very sensitive over his past. he regrets to have been the one that was used to lure and kill the children, being haunted by the fact the last thing they saw was his face. This tempts to leave him vunerable, and make it easy for Afton to possess and take control over his body, because as long as a piece of Afton remains in him, he'll never truly be free. And being surrounded by the ones he tortured because his lover is dating them too is a heavy feat. Despite all this, he still manages to give advice and somewhat comfort to anyone who seeks it, and is genuinely looked up on by the group.

origins
William Afton returned to the final Freddy's restaurant to dismantle the original animatronics so they could not pose a threat to him anymore. However, it turned out they were long gone, having escaped the pizzaria and all that was left were lone spirits from previous murders. They attacked William. Fleeing from the spirits, William escaped into the safe room where Spring Bonnie had been placed for storage. He donned the suit to hide from the ghosts, apparently fooling them. In his arrogance, William stood and laughed at the ghosts while inside Spring Bonnie. However, the faulty mechanisms within Spring Bonnie malfunctioned, causing William to be crushed and sliced by the endoskeleton and gears, killing him. 30 years later, Fazbear's Fright: The Horror Attraction was opened as an homage to The Missing Children Incident and other incidents that made Freddy Fazbear's Pizza infamous. Employees found the withered Spring Bonnie animatronic in one of the safe rooms and reused it for the attraction. There, the animatronic came to life, forming the entity now known as Springtrap. Springtrap survived the burning, and fled into the streets, never to be found by Fazbear entertainment again. He spent a few years like this, untill the rain started to fully rust his endoskeleton, forcing him to collapse in a alleyway, and shut himself off. a week or so passed, untill a young female decided to check out the strange figure she'd been noticing outside her apartment window. while afraid at first, and the ever so slight defensive response of Springtrap not helping, she introduced herself, and offered him to stay at her home for a bit while she figured out how to help him. With a lot of internal struggling, he agreed, and soon enough, she got her mechanical carrier, helping him get inside. little did he know that inside he'd find some familiar faces..3 out of the 4 1993 fazbear crew, Freddy, Bonnie and Foxy to be correct. While the 4 fought and tried to protect their human friend, especially after all the hell Afton had created, they soon realized it wasn't the same guy, and settled down. Everyone soon learned to get along, and Springtrap had managed to fall for Noa, making the decision to stay much easier.
